Simulation Environment
n NS2 simulations to validate literature results
n Explored 3 protocols:
Ø FLOOD: simple broadcast protocol
Ø BCAST: broadcast protocol that reduces packet retransmissions
(do not retransmit of there is no new neighbor that does not yet
know about the data packet)
Ø ODMRP: mesh-based multicast protocol
n The “usual” simulation parameters: area of 1500m x 300m,
50 nodes, 802.11 MAC at 2 Mbps, at low or high mobility.
Ø 1, 2, 5, or 10 senders
Ø 10, 20, 30, 40, or 50 receivers
Ø Each sender sends a 256 byte packet every 500 ms
n Performance Metrics: Packet Delivery Ratio and Packet
Latency
